Small Boss company has cooper- ated with Singapore Biological
Filter Media Research Institute, Shanghai University and Wuhan
University to carry out research and develop- ment of water
treatment filter media since 2004. After years of efforts, Small
Boss has successfully developed a number of new Biological Filter
Medias and obtained 68 national patents for the products including
12 patents for MBBR biological filter media.

At present, Small Boss Company has over 100 high speed production
lines and it’ s capable of carrying out all processes independently
from material, mold ,production process, cutting, packaging, so as
to ensure uniform quality. After years of research and development
and compari- son test of several hundred polymer materials
regarding their biocompatibility and hydrophilcity, Small Boss
eventually determined to choose a kind of HDPE material as the main
ingredient of the biological additive and by modifying the nature
with special formula and adding trace elements such as hydrophilic
groups, better performance was achieved such as excellent
mechanical performance, great shock resistance, appropriate
density, better hydrophilic performance and prolonged service life.
In the meantime, Small Boss has carried out improvement and
innovation of the mechanical equipment and production technology to
make MBBR Filter Media particles better meet the needs of
biological growth, provide more physical attachment points for
microorganisms, facilitate 3D flow of Filter Media in water and
promote rapid attachment, reproduction and growth of microorganisms
in water to form a biological membrane.

After ten years of Study and efforts of production of MBBR filter
media, Small Boss has become the largest manufacturer of MBBR
Fitler Media in China , and Small Boss Filter Media has been
